Measurement of the top quark pair production cross section with a tau lepton in the final state at the center of mass energy of 8 TeV
(2016)This dissertation presents the measurement of the inclusive cross section of the top quark pair production in the final state of a tau lepton with associated jets. The dataset used in this measurement is collected by the ... -
Observation of opposite sign WW with an associated photon production at a center of mass energy of 13 TeV with the ATLAS detector at the LHC
(2022-12)The analysis presented in this thesis expects to provide the first observation of the opposite sign WW with an associated photon process and to measure its fiducial cross section. The analysis uses proton-proton collision ... -
OBSERVATION OF SINGLE TOP QUARK WITH ASSOCIATED Z BOSON PRODUCTION AT THE LARGE HADRON COLLIDER USING THE ATLAS DETECTOR
(2019)The Standard Model of particle physics is the most well tested theory in modern physics. It provides the most fundamental description of the natural world using only a handful of particles and their interactions. At ... -
SEARCH FOR ELECTROWEAK PRODUCTION OF SUPERSYMMETRIC STATES IN NON-UNIVERSAL HIGGS MASS MODEL WITH TWO EXTRA PARAMETERS COMPRESSED SCENARIO WITH THE ATLAS DETECTOR
(2018-05-11)The ATLAS and CMS collaborations announced the discovery of the Higgs boson in July 2012, completing the particle content of the Standard Model. Although the Standard Model is a great triumph, it is not considered to be ... -
SEARCH FOR SUPERSYMMETRY IN FINAL STATES WITH TWO SAME SIGN LEPTONS OR THREE LEPTONS AND JETS WITH THE ATLAS DETECTOR AT THE LHC
(2017-07-07)The Standard Model of particle physics is the culmination of decades of experimental and theoretical advancements to successfully describe the elementary particles and their interactions at low energies, up to 100 GeV. ... -
Searches for new physics with top quarks in the final state and measurement of the differential cross-section of ttbar production in association with additional heavy flavor jets
(2022-05)The Standard Model of particle physics is the most successful theory of elementary particles and their interactions. However, it does not describe some phenomena observed in the experiment, like the presence of dark matter ...
